WILLIAM F. HARTIG, OF EVANSVILLE, INDIANA.

PLOW OR CULTIVATOR SHOVEL.

SPECIFICATION forming part of Letters Patent No. 681,547, dated August 27, 1901.

Application filed June 24, 1901.

To aZZ whom it may concern:

Be it known that I, WILLIAM F. HARTIG, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Plow or Cultivator Shovel, of which the following is a specification.

The present invention relates to a new and useful plow or cultivator shovel, and more particularly to the class of reversible shovels which are so constructed that when one end is worn the device may be turned and the other end used.

The object of the present invention is to improve the devices of this character by employing a novel structure that will turn the soil somewhat on the order of the moldboard of a turning-plow, that will thoroughly pulverize said soil, and at the same time will not become clogged or choked. These objects are accomplished by means of the construction illustrated in the accompanying drawings and described in the following specification.

It will of course be understood that such slight changes may be made from the construction shown and described as fall within the scope of the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a shovel embodying the improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal sectional View. Fig. 4 is an end view.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

The shovel, as shown in the accompanying drawings, comprises a longitudinally-curved blade 10, consisting of two end sections 11, joined together by the contracted neck 12. These sections are twisted substantially upon the longitudinal axis of the blade, said axis being designated by the line A B. By this means said blades will be located in different longitudinally-disposed planes, as is clearly indicated by the lines 0 D and E F, which respectively represent the transverse axes of the sections. Each section is provided upon its opposite side edges with pointed pulverizing projections 13, and the side edges 14 of the neck 12 are each in the form of a continuous curve that extends from the point of one projection on one section to the point of the Serial No. 65,815. (No model.)

corresponding projection on the other, thus forming the throats 15 in the opposite side edges of the blade. The end portion of each section tapers to a central nose 16, and the end edges 17 are sharpened, said edges ex tending from the nose to the points of the pulverizing projections 13. In order to attach the shovel to a cultivator-standard or plowstock, said shovel is provided in its contracted neck with bolt-receiving openings 18.

By the construction as above set forth it will be seen that when the shovel is secured to a'standard or stock the lower section will be inclined in one direction, while the upper section will be inclined in the other direction. Practicallya moldboard is thus formed which throws the soil to one side. The upper and lower side projections thoroughly pulverize the soil, and because of the side throats 15 portions of said soil will pass through between the projections and not only prevent the choking of the intermediate portions of the blade, but also allowing the soil to drop back into the furrow. The draft of a construction of this sort has been carefully measured and found to be much less than devices of this kind having straight sides, and because of the projections at both ends no soil is left uncut in the furrow and the broad upper end turns the soil over close to the plants.

From the foregoing'it is thought that the construction, operation, and many advan tages of the herein-described invention will be apparent to those skilled in the art with out further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advan-' tages of the invention.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. A cultivator-shovel comprising a longitudinally-curved blade consisting of two sections twisted substantially upon the longitudinal axis of said blade, so that their operative faces are located in different longitudinally-disposed planes, and pulverizing projections extending outwardly from the opposite side edges of each section.

2. A cultivator-shovel comprising a longitudinally-curved blade consisting of two sections joined by a contracted neck, said sections being twisted substantially upon the longitudinal axis of the blade so that their operative faces are located in dilferent longitudinally-disposed planes, and pulvervizing projections extending outwardly from the opposite side edges of each section, the projections of said sections being spaced from each other.

3. A cultivator-shovel comprising a longitudinally-curved blade consisting of two sections joined by a contracted neck, said sections being twisted substantially upon the at. A cultivator-shovel comprising a longitudinally-curved blade consisting of two sections twisted substantially upon the longitudinal axis of the blade so that their operative faces will be located in different longitudinally-disposed planes, pointed pulverizing projections located upon the opposite side edges of each section, and a contracted neck connecting said section, the side edges of the neck being each in the form of a continuous curve that extends from the point of one pro jection on one section to the point of the corresponding projection on the other section, the end portion of each section being tapered to a nose and having the end edges sharpened, said edges extending from the nose to the points of the pulverizing projections.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

WILLIAM F. IIARTIG.
